13e it known that I, WILLIAM CHARLES MOORE, a citizen oi' the UnitedStates, residing at New Iberia, in `the parish of Iberia and State ofLouisiana, have invented certain newv and useful Improvements inCentrifugal Machines; and I do declarethe following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention rela-tes to improvements in centrifugal machines forseparating molasses f rom sugar, and more particularly to the rotarybaskets thereof; and it has for its general object to 'provide a rotarybasket for a centrifugal machine embodying such a oonstruction that theseparation and escape of the molasses from the sugar will be materiallyaccelerated, and in consequence the time necessary to separate eachcharge will be shortened and the capacity of the machine Will beincreased, and this without materially increasing the cost of the rotarybasket.

Other objects and advantages of the invention will be fully understoodfrom the following description and claims when taken in conjunction withthe accom pan ying drawings, in Which- Figure l is a detail diametricalsection of so much of a centrifugal liquid-separator as is necessary toillustrate my invention. Fig. is an enlarged detail section showing myimprovements. Fig. 3 is avieiv of the fora minated and sectional annulusof my improvements removed. Fig. 4. is an inverted plan view of thesectional block in which the guide- Ways are formed. Figs. 5 and 6 aresimilar views of modified forms of bloeksections- 7 is a detailperspective view of a blocksection and one of the segments of theforalninated annulus connected together. Fig. 8 is an enlarged detailsection illustrating a modific-ation.

Referring by numerals to said d rawings,and more particularly to Figs. lto '7 thereof, l indicates the casing of a centrifugal machine, which isdesigned to receive the molasses separated from the sugar and isprovided with an outlet 2 for the same, and 3 indicates a eentralupright shaft, both of which may be and preferably are of the ordinaryconstruction,

and 4. indicates the rotary basket, which is iiXed to and is designed toturn with the shaft This basket 4, like the ordinary basket, has'tlieimperforate bottom 5, the inner and outer'foraminated shells G and 7,and the interposed gauze S, to permit the outward passage of molassesand retain the sugar, and

' the inwardly-directed annular portion 9, de-

sign ed to prevent the sugar and molasses from being thrown out of thebasket by centrifugal action.

Asis Well known to those experienced in operatin g centrifugalseparators, the rapid rotation of the basket causes the Wet sugar ormassquete to distribute or spread itself evenly over the side Wall ofthe basket, and when the sugar is of low grade the molasses will notpass through the sugar freely, but on the other hand often forms in alayer of varying thickness on the inner side of the sugar untilgradually forced through the sugar into the casing l. This prolonge theprocess of separation and materially reduces the capacity of the machineand is objectionable for that reason. The rapid rotation of the basket4. also causes the sugar and the molasses to ascend the side of thesame, and I propose to take advantage of such ascension of the sugar andmolasses to accelerate the separation of the same and thereby reduce thetime necessary to separate a charge and increase the capacity of themachine. To this end I provide the block 10 and the foraminated annulnsor plate ll, and preferably connect gauze 13 tothe under side of theplate l1. The block .lO may be in one piece or a plurality of segments,as shown in Fig. 4, and it is beveled on its upper side to conform tothe in Wardly-directed portion 9 of the basket 4, beneath which it isarranged and suitably secured, as illustrated. This block l0 is providedin its under side with grooves l2, which may be radially disposed, asshown in Figs. l to 4, tangentially disposed, as shown in Fic. 5, orcurved, as shown in Fig. 6, and are preferably closed at their innerends by a strip let, increased in Width toward their outer ends, 'asshown, so as to permit the molasses to flow more freely through suchends and thence out of the basket through the upper perforations in theouter shell 7. The foraininated annulus or plate 1l. and the gauze 13,connected ICO molasses to pass to the grooves 12 of said block 10 andcheck the passage of the sugar, asrwill be hereinafter more fullyexplained.

The baskets of centrifugal machines: ats

present in use have inwardly-directed portions 9 for the purpose beforedescribed, and the block 10- and annulus 11 are: formed im segments, asdescribed, in order that they may be readily placed and secured in the'baskets. When, however, my im rovements are.

embodied in anew machine, t ebl'ock l0 and4 annulus 1ly may berespectivelyformed` in; one,` piece. The block 10, when formed; in@ onepiece or of a plurality of segments, servesr in conjunction with thelinwardlydirected' por-1y tion 9 of the: basket', to form an:`inwardly-directed flange 9a, the grooves. 12in the block' l0 being atthe underside of said flange, as shown. When desirable, the;inwardly:div4 rected flange of the basketmay be fernred one piece, asshown in Fig. 8. This flange 9? is provided inits. under sidewithgroovesrla, which communicate at their outer ends,y the upperperforations in the*y outer shellll; Theforaminated annulus er plate l1andthe ganze 13', connected thereto, are.also,employedl in conjunctionwith the flange 9h, they being arranged and suitably secured immediatelybelow the grooved under side of the lian-gez, as shown.

In the practical operation: of thekmaeli-inef ket, and the latter willtakev through the apertures of the plate. 11,. the grooves: of theinwardly-directed liange, and; the apertures of the shell 7, and intothe casinglf, while, the sugar willberetained Within thebasketl by theplate lil.. In virtue of this and the fact) that; a. portion ofi the:vmolasses' will also be forced through the side of the basket it will` beseen that a charge will be quickly separated, and that consequently thecapacity of the machine will bematerially increased. f Itzwilllalsebeiappreciated that my improve ments are, very simple and do not addmatefinally tothey cost of a centrifugal machine, and that theimprovements may be added to dmachines at present in use, as well asernbodied in new machines.r
